Complement-induced phospholipase A2 activation in experimental membranous nephropathy1 See Editorial by Shankland, p. 1204.

Dendritic-cell activation by secretory phospholipase A2.

Dendritic cells (DCs), also referred to as the sentinels of the immune system, induce and coordinate important functions of immune surveillance. DCs acquire immunity-initiating capacity only after a process of maturation usually induced by ligands that bind to members of the tumor necrosis factor (TNF) or toll-like receptor families. Secretory phospholipase A2 (sPLA2), which hydrolyzes the sn-2...

Anti-phospholipase A2 receptor antibody in membranous nephropathy.

The M-type phospholipase A2 receptor (PLA2R) is a target autoantigen in adult idiopathic membranous nephropathy (MN), but the prevalence of autoantibodies against PLA2R is unknown among Chinese patients with MN. Here, we measured anti-PLA2R antibody in the serum of 60 patients with idiopathic MN, 20 with lupus-associated MN, 16 with hepatitis B (HBV)-associated MN, and 10 with tumor-associated ...

Phospholipase A2 receptor antibodies in membranous nephropathy: unresolved issues.

The discovery of theM-type phospholipase A2 receptor (PLA2R) as a major antigen in idiopathic membranous nephropathy (iMN) was a breakthrough and established iMN as an autoimmune disease.1 Subsequent studies confirmed that antibodies against PLA2R were present in approximately 70% of incident iMN patients (reviewed by Hofstra and Wetzels2). The potential role ofmeasuring PLA2R antibodies for cl...

Idiopathic membranous nephropathy and anti-phospholipase A2 receptor antibodies.

Anti-phospholipase A2 Receptor Antibody and Immunosuppression in Membranous Nephropathy: More Evidence for Pathogenicity of Anti-phospholipase A2 Receptor Autoantibodies.

In the 6 years since the discovery of anti-phospholipase A2 receptor (anti-PLA2R) antibodies in the majority of patients with primary membranous nephropathy (MN),1 our understanding of the role of anti-PLA2R in clinical disease has evolved rapidly. The initial small retrospective clinical studies indicated that anti-PLA2R levels could be modulated by immunosuppression.1,2 Levels decreased in ad...
